Epidemiology and Pathogenesis of Plague Model
Product Code : JC-BE-6191
The Epidemiology and Pathogenesis of Plague Model from Jaincolab is a three-dimensional teaching model that illustrates the transmission cycle and disease progression of plague.
It is used in microbiology and public health courses to explain how Yersinia pestis spreads from rodents to humans and progresses through its clinical forms.
What the Concept States
| Parameter | Details |
|---|---|
| Causative Organism | Yersinia pestis, a Gram-negative coccobacillus showing characteristic bipolar ("safety pin") staining |
| Transmission Cycle | Maintained in wild rodent populations and transmitted to humans through the bite of infected fleas, chiefly Xenopsylla cheopis |
| Bubonic Plague | The most common form; presents with painful, swollen lymph nodes called buboes near the flea bite site |
| Septicemic Plague | Occurs when the bacteria spread into the bloodstream, causing widespread tissue damage and shock |
| Pneumonic Plague | The most severe form; spreads person-to-person via respiratory droplets and causes rapidly progressive pneumonia |
Key Features
- Illustrates the rodent-flea-human transmission cycle of plague
- Shows the progression from bubonic to septicemic and pneumonic plague
- Explains the bipolar staining appearance of Yersinia pestis
- Durable, exam-oriented construction for repeated classroom use
- Compact benchtop format suitable for laboratories and lecture halls

Frequently Asked Questions
Q1. What does the Epidemiology and Pathogenesis of Plague Model demonstrate?
A. It demonstrates the transmission cycle and disease progression of plague caused by Yersinia pestis.
Q2. How is plague transmitted to humans?
A. It is transmitted mainly through the bite of infected fleas that have fed on infected rodents.
Q3. What is bubonic plague?
A. Bubonic plague is the most common form, presenting with painful, swollen lymph nodes called buboes near the flea bite site.
Q4. What is pneumonic plague?
A. Pneumonic plague is the most severe form, spreading person-to-person via respiratory droplets and causing rapidly progressive pneumonia.
Q5. Who uses this model?
A. Microbiology, medical, and public health students and faculty use it to study plague epidemiology and pathogenesis.
